DEVICE FOR PRODUCING FILAMENTOUS OB FILMY CELL-ULOSE BODIES.

Application filed March31,'1913.

To u/l whom it may concern.

Be it known that I.-"Atfovs'rix-flfnLLnmx, a citizen of the Republic of France, ing at Trouville Boulevard dHautpoul, (Seine Inferieure,) in the Republic of France, chemistrhave invented certain new and useful Improve.- ments in Devices for Producing Filamentous or Filmy Cellulose Bodies, ot" which the following is a specification.

My invention relates to a new process and device for producing filamentous or filmy this process a solution of cellulose matter is injected through an unlimited number of capillary holes, into a current of coagulating and fixing liquid, which is running at a speed that may be regulated at will with reference to the speed of the cellulose solution when issued from said holes. so as to carry the filaments away in the direction of the current gradually as they are produced. By giving the coagulating liquid a higher speed than to the cellulose solution, the filaments while forming are givena sort of wire-drawing and may thus be obtained of a very high grade of fineness. My process offers besides the advantage of continuously carrying away all solid matters as they are precipitated or set free, so as to allow the. filaments \ccording to formed to take rise within a constantly renewed and perfectly clean medium. It enables the production at a low price of enormous quantities of filamentous (tliready) or filmy matter (ready for spinning or for being purified and for being used for manufacturing artificial sill: etc.). Mechanical means, such as rollers for instance. which act upon the filaments as they are delivered from the device, may also be used for giving the latter a sort of wiredrawing as they issue from the device.

The accompanying drawings show as an example a device arranged for working my new process.

Figure 1 is a vertical sectional view, Fig. 2 is a plan view with the cover removed and Fig. 3 is a detailed ele 'ation and sectional view showing a draw-plate.

'My new device consists of a tapered vessel 1 with a cover '2 and a removable central tube 3 around which a great number of angled tubes 4: are formed in an inclined direction. Upon the mouth of each of these tubes is fitted a draw-plate formed as Specification of Letters Patent.

shown in Fig. 3, of a thin perforated plate .which is pressed between two frames 6 This plate is preferably made of great number of capiland 7. .platinum and bears a lary holes. grooves may be formed on the inside of the trame'so as to engage the thin plate 5 and to assure its adherence.

The cellulose solution enters the vessel 1 undera convenient pressure (over 30 pounds per square inch) through one or more inlets S. In the example shown, the vessel is divided into a number of compartments by means of partitions 9 which fit against the tube 3 and against the cover 2. Each of the compartments is fed through one of the tubes 8 so as to allow of disuse of any one of the compartments, should it be required to .do so. The center tube 3 is connected at its top to a vessel containing some coagulant and fixing fluid, while its lower part is connected to a. receiving tank (not shown) able to separate the cellulose filaments from the liquid that carries them along. This separating may be stance by means of a perforated guide retaining the filaments but allowing the liquid to escape sidewise.

In operation. the cellulose solution is projected at a high rate of speed through all of the capillary holes, in a great number of jets which are instantly coagulated and fixed by the action of the liquid flowing alSO at a high speed through the tube 3 so as to form filaments. These filaments form in the column of the liquid a. cylindrical bunch which is carried away by the liquid.

By regulating the relative speed of the solutions issuing from the draw-plates'and of the liquid moving through the tube 3, for instance by varying the pressure acting upon the cellulose solution. the height of fall. of the liquid, the section of the outlet underneath the device, etc, 1 may attain a drawing of the filaments produced, drawing which will be the more efiective, the more the speed of the liquid will exceed that of the cellulose solution jets, leaving the drawplate.

The drawing desired may also be'secured by the means of mechanical draw-pieces (not shown) such as rotating rollers. etc.. which are fitted at the outlet of the tube 3 and act upon the filamentous material so as to carry it away at a. speedwhich may be regulated at will. By reducing the speed of carry- Thin ribs and corresponding Y done for ining the filaments long, thefila'ments are given a greater elasticity.

It is to be understood that the shape of the vessel employed, as Well as that of its central tube, the smaller tubes and the drawplates may be modified at Will without interfering with the idea of my'invention; it

' is not necessary moreover to arrange the draw-plates around an axis, nor to produce a cylindric bunch of filaments; they might bedisposed for instance on a plane surface and be preferably given a conveniently inclined direction to that of the current, so as to produce a plane filamentous bunch.

The draw-plates instead of having capil-v lary holes of a circular'section boredtherein, may carry extremely fine slots so as to produce cellulose films. The vfilaments or films obtained may be modified or be treated by any process in use.

laims: g ,1. A device for manufacturing filamentous or filmy cellulose bodies comprising a vessel of annular section, having in its tubular inner partition apertures, plates bored with small holes fitted in sald apertures obplates fitted in such sure into said vessel, and means for keeping a current of coagulant liquid moving through the channel formed by said inner partition of the vessel.

2. A device for manufacturing filamen tens or filmy cellulose bodies comprising an .annularly formed vessel having between'its outer and inner walls radial partitions which divide it-into compartments, and having in its inner tubular wall apertures, finely bored apertures obliquely to the axis of the vessel, means for leading a coagulable liquid under pressure separately into each'of the compartments of said vessel,

and meansv for keeping a current of coagulant liquid moving through the channel formed by said inner Wall of the vessel.
